High blood testosterone levels associated with increased prostate cancer risk

Researchers found a significant association between high blood testosterone levels and an increased risk of prostate cancer in older men. The study, which followed over 3,000 men for 40 years, also showed that the protein sex hormone-binding globulin (SHBG) was associated with a slightly decreased risk for prostate cancer.
